IMPROVEMENT IN CENTRIFUGAL SUGAR-MACHINES.

Specification forming part of Letters Patent No. 181,208, dated August15, 1876; application filed June 21, 1876.

To all whom it may concern Be it known that I, EMILY ROGHOW, of

Brooklyn, in the county of Kings and State of New York, have invented anew and useful Improvement in Centrifugal Sugar-Machines, of which thefollowing is a specification:

The object of this invention is to so constructthe receiving-chambers ofa centrifugal sugar-machine that the slabs of sugar formed thereinwill,by a series of grooves, be divided on their surfaces into cubes orblocks of suitable form and size for greater convenience in subsequentseparation.

The plates of sugar now produced in machines of the kind described inthe Letters Patent No. 157,595, and in other machines of similar kind,must be cut into blocks for table and family use, and expensivecutting-machines are now used for that purpose.

My invention consists in forming projecting ribs on the removablepartitions of the receiving-drum, and in thereby grooving the slabs ofsugar formed therein, so that they may be readily broken into cubes,blocks, or pieces of the desired size and shape. The labor of cutting isthus entirely dispensed with, and the sugar can even be packed formarket in the form of grooved slabs, and reduced into regular blocks bythe consumer, as occasion may require.

1n the accompanying drawing, Figure 1 represents a vertical centralsection of a centrifugal machine provided with my improvement.

Fig. 2 is an inner face view of a section of the drum containing myinvention. Fig. 3 is a horizontal section thereof; and Fig. 4, aperspective view, on an enlarged scale, of a plate of sugar groovedaccording to my invention.

Similar letters of reference indicate corresponding parts in all thefigures.

The letterA representsa section of the outer drum of a centrifugalsugar-machine provided with a series of horizontal or other partitions,B B, substantially as described in the Patent No.157,595; but theinvention is equally applicable to other styles of centrifugal orsugarmolding machines. Between these partitions the sugar is formed intoplates or flat cakes of considerable extent. 1 form on the faces of thepartitions B B projecting ribs to a, at such distances apart, and atsuch angles to one another, that the grooves formed by them in theplates or slabs of sugar molded within the drum will partly divide thesame into cubes or pieces of the desired size and form and, as clearlyindicated in Fig. 4, the division of the slabs being such that with asmall effort they will be finally reduced into blocks, I prefer to formthese ribs on opposite sides of each partition B, as shown in Fig. 2;but for many purposes it may suffice to have but one face of eachpartition provided with such ribs. When the double system of ribs isused, it will be necessary to introduce false partitions B B", havingribs 0,, into the drum close to the walls thereof, as in Figs. 1 and 2,for the purpose of grooving the outer faces of the outermost sugarslabs. The ribs (1 a I prefer to make tapering for greater ease ofwithdrawal from the sugar.

1 claim as my invention- 1. In combination with the drum of acentrifugal machine, the plates B B, made with projecting ribs a,substantially as specified.

2. In combination with the drum A and ribbed partitions B B, the falsepartition B", substantially as specified.
